Everything was working fine earlier and my machine other machine is able to run sync fine with the same app. I am not sure how to ge about debugging this.

GitHub has invalidated SSH keys today. Log on to your account for the project and re-approve the keys.

A security vulnerability was recently discovered that made it possible for an attacker to add new SSH keys to arbitrary GitHub user accounts. This would have provided an attacker with clone/pull access to repositories with read permissions, and clone/pull/push access to repositories with write permissions. As of 5:53 PM UTC on Sunday, March 4th the vulnerability no longer exists.

While no known malicious activity has been reported, we are taking additional precautions by forcing an audit of all existing SSH keys.

I just resolved the same issue on a repo of mine. I had initially cloned the repo in Terminal with git://github.com/djs070/reservedpaths, before switching to Github for Mac client. I went to repo settings in Github for Mac and changed the Primary Remote Repository setting to the format git@github.com:djs070/reservedpaths.git, and was then able to sync to remote without any trouble.
